Step 3: Baking the Shells.
Preheat oven to 325-350 F. and place yellow corn tortillas on the forms. Bake until they begin to turn a darker color, about ten minutes, but remove immediately, as they will burn if left in the oven any longer.
Note: Be sure to use oven mitts or heat proof pads to remove the shells from the oven as they will be very HOT!!!
